An anonymous reader quotes a report from Ars Technica: For years, people in cars stuck behind blue delivery trucks in traffic have echoed media reports criticizing Amazon for clogging American roadways. It's well-known that the Amazon drivers steering these fleets of trucks and vans don't actually work for Amazon but are hired by companies contracted by Amazon, and Amazon has repeatedly denied liability for any dangerous driving reported, though. Because Amazon has contracts with more than 50,000 firms, just how dangerous Amazon's contracted drivers really are remains a question that is hard to track. However, The Information reported last year that horrific car crashes are part and parcel of Amazon's culture of convenience. And then more recently, The Wall Street Journal provided another window into how deadly America's favorite speedy delivery service can be. Since 2015, WSJ reported this week, "Trucking companies hauling freight for Amazon have been involved in crashes that killed more than 75 people."

To arrive at this number, WSJ partnered with Jason Miller -- a Michigan State University professor who researches transportation safety -- to analyze various sources of government data from "3,512 trucking companies that were inspected by authorities three or more times while hauling trailers for Amazon since February 2020." The resulting report, WSJ said, "for the first time showed how the safety performance of Amazon's trucking contractors compared with their peers." And their results didn't appear good for Amazon. For example, a review of Department of Transportation data on unsafe driving scores of more than 1,300 Amazon trucking contractors from February 2020 to early August 2022 found that contractors who worked the most with Amazon were "more than twice as likely as all other similar companies to receive bad unsafe driving scores." WSJ also found evidence of dozens of companies that Amazon contracted that had "conditional" ratings, which is like DOT putting them on probation -- a black mark that typically alienates most firms from contracting them. One Illinois-based company contracted by Amazon "scored worse than the level DOT officials consider problematic" every month of WSJ's review period. "First and foremost, the insinuation that Amazon puts more value on meeting deadlines than on human lives is categorically false," said Amazon spokesperson Kelly Nantel. "Any accident involving one of our partners or community members is a tragedy, and we always work with our contractors to prevent accidents or learn from them, so they don't happen again."

The safety director of Amazon's freight unit, Steve DasGupta, noted that Amazon contractors had "a rate of fatalities per vehicle mile about 7 percent lower than the industry average in 2020." The company also told said it has "suspended all contractors involved in car crashes described in WSJ's report, suspended or terminated 80 percent of contracts where WSJ found unsafe driving scores, and made changes to its screening process," reports Ars.

A person may take knowing the local time for granted, but an official review revealed that there is no single, accurate map showing the nation's time zones and local observance of Daylight Saving Time. CNN reports: Federal transportation officials are now at work creating an accurate map of the nation's time zones, according to a report by the inspector general for the Department of Transportation. The issue came up, the inspector general's office said, after the US Senate passed legislation this year to end the biannual time turn by making Daylight Saving Time permanent.

Investigators found no single map accurately showing the boundaries nationwide and said several sources of time information on the DOT website contained errors, such as inaccurately noting the time practices in some localities. For example, one map incorrectly identifies a deviation in Nevada: "Elko County, NV is shown as the location that changed time zones rather than the correct location, the city of West Wendover."

"The official boundaries are narratively described [in federal regulations] with various types of coordinates and geographic features such as lines of longitude, State or county lines, and rivers," the report stated. The inspector general report said the Transportation Department is responsible for keeping the clock because of the importance of time to travel. It said the original five time zones have expanded to nine.

An anonymous reader quotes a report from TechCrunch: Nvidia is gearing up to deliver Drive Thor, its next-generation automotive-grade chip that the company claims will be able to unify a wide range of in-car technology from automated driving features and driver monitoring systems to streaming Netflix in the back for the kiddos. Thor, which goes into production in 2025, is notable not just because it's a step up from Nvidia's Drive Orin chip. It's also taking Drive Atlan's spot in the lineup. Nvidia is scrapping the Drive Atlan system on chip ahead of schedule for Thor, founder and CEO Jensen Huang said Tuesday at the company's GTC event. Ever in a race to develop bigger and badder chips, Nvidia is opting for Thor, which, at 2,000 teraflops of performance, will deliver twice the compute and throughput, according to the company.

"If we look at a car today, advanced driver assistance systems, parking, driver monitoring, camera mirrors, digital instrument cluster and infotainment are all different computers distributed throughout the vehicle," said Nvidia's vice president of automotive, Danny Shapiro, at a press briefing Monday. "In 2025, these functions will no longer be separate computers. Rather, Drive Thor will enable manufacturers to efficiently consolidate these functions into a single system, reducing overall system cost." One chip to rule them all. One chip to help automakers build software-defined autonomous vehicles. One chip to continuously upgrade over-the-air. Further reading: Nvidia Announces Next-Gen RTX 4090 and RTX 4080 GPUs

Sebastian Thrun, the CEO of Kitty Hawk, informed employees on Wednesday the company was laying them off, according to a news report. The company also posted the news on its LinkedIn page. From the report: Sources inside the company told Insider that Kitty Hawk had recently wound down work on its most recent flying-car project, Heaviside, and reverted to research-and-development mode with Google co-founder Larry Page more closely involved with the work. However, it appears the company couldn't see a way forward. Laid-off staff have been given four months of severance pay, an employee said. Thrun, a self-driving car pioneer and a Google veteran, founded Kitty Hawk in 2010, and Page financially propped it up. Insiders said Page remained the sole bankroller of Kitty Hawk throughout its lifetime. He became increasingly hands-off over the years, though he would involve himself in newer projects as they sprung up, including an internal initiative to make flying cars run more quietly. The company produced several prototype models of its flying cars, including Flyer, which the company shuttered in 2020. Heaviside, its most recent model, was designed to be quieter for flying in densely populated environments. In 2019 the company also spun up Wisk, a joint venture between Kitty Hawk and Boeing, which will continue.

An anonymous reader quotes a report from Ars Technica: The US National Transportation Safety Board (NTSB) yesterday recommended that all new vehicles be equipped with alcohol detection systems that can stop people from driving while drunk. The NTSB can't issue such a regulation on its own but urged the National Highway Traffic Safety Administration (NHTSA) to do so. The NTSB said it "is recommending measures leveraging new in-vehicle technologies that can limit or prohibit impaired drivers from operating their vehicles as well as technologies to prevent speeding." If adopted, this would require "passive vehicle-integrated alcohol impairment detection systems, advanced driver monitoring systems or a combination of the two that would be capable of preventing or limiting vehicle operation if it detects driver impairment by alcohol," the NTSB said. The agency urged the NHTSA to "require all new vehicles to be equipped with such systems."

Under a US law enacted last year, the NHTSA is already required to examine whether it can issue this type of rule. While drunk driving is a longstanding problem that has caused many deaths, the NTSB said its recommendation was spurred by its investigation into one crash that killed nine people -- including seven children -- in January 2021 on State Route 33 near Avenal, California. On that two-lane highway with a speed limit of 55 mph, an SUV driver leaving a New Year's Day gathering "was driving at a speed between 88 and 98 mph," the NTSB report said. [...]

Section 24220 of the Bipartisan Infrastructure LawSection 30111 of Title 49 in US law, it can delay issuing a rule for three years and submit annual reports to Congress describing the reasons for not issuing the rule. Each annual report would also have to contain an update on "the deployment of advanced drunk and impaired driving prevention technology in vehicles." In writing the law, Congress noted that "in 2019, there were 10,142 alcohol-impaired driving fatalities in the United States involving drivers with a blood alcohol concentration level of .08 or higher, and 68 percent of the crashes that resulted in those fatalities involved a driver with a blood alcohol concentration level of .15 or higher." Congress also cited a study by the Insurance Institute for Highway Safety estimating that "advanced drunk and impaired driving prevention technology can prevent more than 9,400 alcohol-impaired driving fatalities annually."

Descending up to 40 meters beneath the Baltic Sea, the world's longest immersed tunnel will link Denmark and Germany, slashing journey times between the two countries when it opens in 2029. CNN Travel reports: After more than a decade of planning, construction started on the Fehmarnbelt Tunnel in 2020 and in the months since a temporary harbor has been completed on the Danish side. It will host the factory that will soon build the 89 massive concrete sections that will make up the tunnel. "The expectation is that the first production line will be ready around the end of the year, or beginning of next year," said Henrik Vincentsen, CEO of Femern A/S, the state-owned Danish company in charge of the project. "By the beginning of 2024 we have to be ready to immerse the first tunnel element."

The tunnel, which will be 18 kilometers (11.1 miles) long, is one of Europe's largest infrastructure projects, with a construction budget of over 7 billion euros ($7.1 billion). [...] It will be built across the Fehmarn Belt, a strait between the German island of Fehmarn and the Danish island of Lolland, and is designed as an alternative to the current ferry service from Rodby and Puttgarden, which carries millions of passengers every year. Where the crossing now takes 45 minutes by ferry, it will take just seven minutes by train and 10 minutes by car. The tunnel, whose official name is Fehmarnbelt Fixed Link, will also be the longest combined road and rail tunnel anywhere in the world. It will comprise two double-lane motorways -- separated by a service passageway -- and two electrified rail tracks. "Today, if you were to take a train trip from Copenhagen to Hamburg, it would take you around four and a half hours," says Jens Ole Kaslund, technical director at Femern A/S, the state-owned Danish company in charge of the project. "When the tunnel will be completed, the same journey will take two and a half hours."

"Today a lot of people fly between the two cities, but in the future it will be better to just take the train," he adds. The same trip by car will be around an hour faster than today, taking into account time saved by not lining up for the ferry.

Uber said on Monday a hacker affiliated with the Lapsus$ hacking group was responsible for a cyber attack that forced the ride-hailing company to shut several internal communications temporarily last week. From a report: Uber said the attacker had not accessed any user accounts and the databases that store sensitive user information such as credit card numbers, bank account or trip details. "The attacker accessed several internal systems, and our investigation has focused on determining whether there was any material impact," Uber said, adding that investigation was still ongoing. The company said it was in close coordination with the FBI and the U.S. Department of Justice on the matter. Friday's cybersecurity incident had brought down Uber's internal communication system for a while and employees were restricted to use Salesforce-owned office messaging app Slack. Uber said the attacker logged in to a contractor's Uber account after they accepted a two-factor login approval request following multiple requests, giving the hacker access to several employee accounts and tools such as G-Suite and Slack.

"Transportation is going to electrify much faster than people realize," says Rick Luebbe, chief executive officer of Group14 Technologies.

So this weekend the Seattle Times paid a visit to their small manufacturing plant in rural Western Washington working on becoming one of the companies supplying a crucial component: Inside this building, carbon is infused with a silicon gas to produce a black powdery substance that high-profile investors hope will be a key component of the next generation of electric car batteries enabling them to travel farther between plug-ins, recharge faster and cost less. "It's transformational," said Rick Luebbe, chief executive officer of Group14 Technologies, which opened the Maltby plant in 2021 and has raised $441 million in funding. The company employs nearly 100 people, and the industrial workplace north of Woodinville has the excitement of a startup company. A research laboratory is under construction in one corner of the building as production is underway elsewhere.

Group14 is one of more than 20 companies launched in a global quest to improve the lithium-ion battery — mainstay of the fledgling electric car industry — by including more silicon.... Within the next decade, two companies plan to make Washington a hub of this emerging technology. Group14, which has drawn Porsche AG as a lead investor, and Sila, an Alameda, California, company that is partnering with Mercedes-Benz, both have announced plans to open large-scale plants east of the Cascades in Moses Lake....

The silicon technology also has applications for many other battery-powered products ranging from cellphones that can last longer between charges to drones and aircraft that could stay aloft for more hours of flight... Company officials at Group14 and Sila say they have developed silicon products that can be blended with graphite — or replace it entirely — without unduly compromising battery life.... "Generally, every customer we're working with is getting the cycling they need for commercial deployment," Luebbe said. Gene Berdichevsky, Sila's chief executive, said Sila's technology, also proprietary, "achieves and exceeds" automotive industry specification even when silicon entirely replaces graphite.

Some automotive companies are betting that silicon does have an important role to play in the next generation of batteries... Mercedes-Benz AG, which this year announced it's opening a new battery plant in Alabama, invested in Sila in 2019. Then, last May, the company announced it would use the Sila silicon technology for electric G-Class vehicles that will start production in the middle of this decade. Uwe Keller, directory of battery development at Mercedes-Benz AG, said his company is involved in extensive research with Sila's silicon product to determine how it best can be incorporated into a next generation of batteries.

But he expects Sila's technology will boost electric car battery range by 15 to 20%....

Berdichevsky, Sila's chief executive, who worked at Tesla in its early years and co-founded Sila in 2011, said his company plans to start producing silicon product from Moses Lake to send to Mercedes-Benz in the second half of 2024.

"Whirring as it powered up, a hoverbike lifted directly into the air in Michigan, video shows."

That's the lead from one news report about a big debut at a U.S. auto show in Detroit: a gasoline-and-electric powered hoverbike (using a Kawasaki motor) created by Japanese manufacturing company AERWINS Technologies. They've already started selling them in Japan, and they're now also hoping to sell a smaller version in America in 2023. The hoverbike flies for 40 minutes, Reuters reports, and can reach speeds of up to 62 miles per hour (100 kph). (They added that the bike drew "perhaps inevitable comparisons to the speeder bikes of Star Wars.")

From McClatchy news services: Video from WXYZ's Facebook shows the hoverbike's flight. The test rider checks the vehicle then signals with a fist pump. The engines power up, whirring louder and louder until the bike lifts off. The hoverbike flies back and forth, slightly faster as the ride goes on, then lands smoothly to the ground, video shows. "I feel like I'm literally 15 years old and I just got out of Star Wars," the test rider told Reuters. "It's awesome! Of course, you have a little apprehension, but I was just so amped. I literally had goosebumps and feel like a little kid...."

The price of a hoverbike? Only $777,000 according to current estimates, though the company hopes to get the cost down to about $50,000, The Detroit News reported.
The Detroit News adds this about the company's founder/CEO: As a boy, Shuhei Komatsu loved Star Wars movies, especially the lightning-fast land speeders. So when he grew up, he decided to make one of his own, he said.

"I wanted to make something from the movie real," Komatsu said. "It's a land speeder for the Dark Side...."

Komatsu said his company will make its public offering of stock on the NASDAQ exchange in November.... He said he's hoping the U.S. government classifies its XTURISMO as a non-aircraft.... He said he thinks consumers will buy the machine for recreation, and governments will buy it for law enforcement and for inspecting infrastructure. "I hope that in the future, people will use it for every day," he said.

The world's freight-carrying trucks and ships use GPS-based satellite tracking and navigation systems, reports ZDNet. But "Criminals are turning to cheap GPS jamming devices to ransack the cargo on roads and at sea, a problem that's getting worse...." Jammers work by overpowering GPS signals by emitting a signal at the same frequency, just a bit more powerful than the original. The typical jammers used for cargo hijackings are able to jam frequencies from up to 5 miles away rendering GPS tracking and security apparatuses, such as those used by trucking syndicates, totally useless. In Mexico, jammers are used in some 85% of cargo truck thefts. Statistics are harder to come by in the United States, but there can be little doubt the devices are prevalent and widely used. Russia is currently availing itself of the technology to jam commercial planes in Ukraine.

As we've covered, the proliferating commercial drone sector is also prey to attack.... During a light show in Hong Kong in 2018, a jamming device caused 46 drones to fall out of the sky, raising public awareness of the issue.
While the problem is getting worse, the article also notes that companies are developing anti-jamming solutions for drone receivers, "providing protection and increasing the resiliency of GPS devices against jamming attacks.

"By identifying and preventing instances of jamming, fleet operators are able to prevent cargo theft."

The Drive reports; Sir Jony Ive — the man designed the original iMac, iPod, iPhone, and iPad during his 22 years as Apple design chief — has claimed new-car buyers will drive demand for physical buttons to return in automotive entertainment systems.

In recent years, car companies such as Tesla and Volkswagen have progressively moved to remove physical switches from their vehicle's interiors, replacing them with 'haptic' touch-sensitive buttons, or moving a majority of the controls into a central touchscreen. Speaking at a panel session at a conference in the US — alongside Apple CEO Tim Cook and Laurene Powell Jobs (widow of Apple co-founder Steve Jobs) — Ive said there are merits to the design of multi-touch screens, but car buyers will demand for physical controls to return.

"I do think there are fabulous affordances with interfaces like, for example, multi-touch [the technology allowing for pinching and zooming on phone screens]," Ive said. "But we do remain physical beings. I think, potentially, the pendulum may swing a little to have interfaces and products that will take more time and are more engaged physically."

When the panel's moderator — journalist Kara Swisher — asked if Ive was referring to cars, the former Apple design boss responded, "for example".
The article also reports that "Apple's secretive autonomous car project is believed to be continuing behind closed doors, with the tech giant reportedly employing 5000 staff members to work on a new electric car."

An anonymous reader quotes a report from CNN: French railway company SNCF and train manufacturer Alstom have unveiled the first completed TGV M, a next-generation high-speed double-decker train that features a longer, more aerodynamic nose -- perfect for hurtling across the French countryside. Alstom dubbed the new train "the TGV of the future." TGV stands for Train a Grand Vitesse, meaning high-speed train. This swanky new design will premiere on the Paris rail network in 2024 and across the country over the following 10 years.

TGV is one of the world's most famous high-speed train brands and has been a staple of European rail travel since the early 1980s. Back in 2018, SNCF, the state-owned French railway company which controls TGV, ordered 100 TGV M trains (also known as Avelia Horizon trains) at a cost of 2.7 billion euros (around $2.7 billion). An additional 15 trains were ordered in August 2022. The majority of the trains will operate within France, but Alstom has said 15 will ride the rails internationally. TGV M will operate at the same maximum speed as the previous generation of TGV trains -- 350 kilometers per hour (nearly 220 mph). "In 2022, we don't want to go faster," said Alstom spokesperson Philippe Molitor told CNN Travel, explaining that the goal instead is high speed trains that accommodate more people while consuming less energy.

TGV M trains don't just have 40.5-centimeter (15.9-inch) longer noses than their predecessors, they're bigger all round. Roomier carriage interiors can accommodate up to 740 seats, compared to the current maximum of 634. TGV Ms also got what manufacturer Alstom calls "unprecedented modularity," meaning the train's interior configuration can be easily adjusted. A carriage can be converted from second class to first class and back again, or adapted to allow space for oversized luggage or bikes. There will also be dedicated on-board passenger social areas to offer variation and flexibility on longer journeys. According to Alstom, the design improves TGV's current energy efficiency and carbon footprint, with 97% of the train's components now recyclable. It also boasts better accessibility -- there will be a lifting platform to allow wheelchair users to independently board the train, and an on-board sound system to aid visually impaired travelers. Larger windows will make the most of views while the TGV's lighting will adapt depending on natural light outside.

Autonomous tech developer Nuro is teaming up with Uber Eats in a long-awaited partnership that will see the company's latest robot take over the delivery of food to app users. Autoweek reports: The two companies signed a 10-year contract just a few days ago, paving the way for a wider rollout of Nuro's driverless delivery robots, which have been operating on a limited scale in several cities. The partnership will kick off slowly, with Nuro deploying its robots to Houston and Mountain View, California, as a start, before the service makes a wider debut in the Bay Area.

Perhaps more importantly, Nuro's delivery robots will allow Uber Eats to not have to pay a human driver, which is something that company has been working toward for years as part of its primary business as well. However, the lagging development of Level 4 and Level 5 autonomy, once widely expected to arrive around 2020, had stalled ambitions for Uber, which has struggled with profitability through normal operations with independent contractor drivers. Nuro delivery robots enjoyed renewed interest from business partners in the early months of the pandemic, but the company's technology is now being viewed as a cost saver for operators rather than a method of more sanitary delivery.

Of course, a limited rollout in two cities plus plans to launch in the Bay Area won't transform Uber Eats' business model overnight. This could take years even with an unlimited supply of Nuro delivery robots -- with regulatory approval still being the major impediment. That's because commercial driverless permits are granted on a state-by-state basis, in addition to city and county approvals, which were hard enough for Nuro to obtain in the Bay Area, where Level 4 robotaxis are being tested. Nuro will need to focus its efforts in those areas where traffic is suitable for its robots.

The ship that would have become the world's largest cruise liner has been scrapped before it ever had the chance to take its maiden voyage. Gizmodo reports: Global Dream II was slated to carry 9,000 passengers and was built by German-Hong Kong shipbuilding firm MV Werften to the tune of nearly $US1.4 ($2) billion, according to the Daily Mail. It was nearly finished when the company went bankrupt at the start of this year. Since that happened, no buyer has stepped up to buy the 20-deck, 341.99 m-long monstrosity. That means it's now destined for the scrap heap. The Mail says that Global Dream II also features an outdoor waterpark and a movie theatre.

The capacity of this ship blows the second largest ship, the Oasis-class Wonder of the Sea which is owned and operated by Royal Caribbean, out of the water (I love a good pun). The Wonder of the Seas has a passenger capacity of only 6,988. Pathetic. Despite the $US1.4 ($2) billion put out to build this behemoth, the ship still needs about $US230,000,000 ($319,286,000) worth of work. Apparently, it is structurally complete, but equipment and passenger facilities still need to be finished. Eagle-eyed readers will have noted the "II" in the ship's name. Yes, there is a twin Global Dream, but it hasn't been given the ax... yet. The Mail reports that right now the two ships are being stored in a German shipyard in Wismar. However, that yard will soon be used to build military vessels. That means the Global Dreams have to be out of there by the end of next year.

Rolls-Royce has ended its involvement in a project by Boom Supersonic to develop a faster-than-sound passenger airliner, leaving unclear the powerplant options available to Boom. FlightGlobal reports: "We are appreciative of Rolls-Royce's work over the last few years, but it became clear that Rolls' proposed engine design and legacy business model is not the best option for Overture's future airline operators or passengers," Boom said on 7 September. "Later this year, we will announce our selected engine partner and our transformational approach for reliable, cost-effective and sustainable supersonic flight."

Earlier in the day, news broke that R-R had backed out of the Boom project. "We've completed our contract with Boom and delivered various engineering studies for their Overture supersonic program," the UK engine manufacturer says. "After careful consideration, Rolls-Royce has determined that the commercial aviation supersonic market is not currently a priority for us and, therefore, will not pursue further work on the program at this time. It has been a pleasure to work with the Boom team and we wish them every success in the future."

Boom, with offices in Denver, has been developing a supersonic aircraft called Overture that it says will carry up to 80 passengers and cruise at Mach 1.7. It initially intended for Overture to have two engines, but recently changed to a four-engined design. The company has been targeting first flight of Overture in 2026 and first delivery in 2029. "Overture remains on track to carry passengers in 2029, and we are looking forward to making our engine announcement later this year," Boom says.

The Los Angeles Unified School District (LAUSD) has confirmed it was hit by a ransomware attack that is causing ongoing technical disruptions. From a report: LAUSD is the second largest school district in the U.S. after the New York City Department of Education. The LAUSD serves over 600,000 students spanning from kindergarten through 12th grade at over 1,000 schools, and employs more than 26,000 teachers. The district said on Monday that it was hit by a cyberattack over the weekend, which it later confirmed was ransomware.

Although the attack caused "significant disruption" to LAUSD's infrastructure, the district said it will resume classes on Tuesday -- after observing Labor Day on Monday -- while it works to restore impacted services. LAUSD said that it does not expect technical issues to impact transportation, food or after-school programs, but noted that "business operations may be delayed or modified." It warned that ongoing disruptions include "access to email, computer systems, and applications," while a post from Northridge Academy High, a school in the district, confirmed that teachers and students might be unable to access Google Drive and Schoology, a K-12 learning management system, until further notice.

In an article published by the Atlantic, writer and Director of Film and Media Studies at Washington University in St. Louis, Ian Bogost, claims e-bikes have an identity crisis and "represent not the fusion of two modes of transit, but a conflict between them." Here's an excerpt from his report: I'd like to drive less, exercise more, commune with nature, and hate myself with a lesser intensity because I am driving less, exercising more, and communing with nature. One way to accomplish all of these goals, I decided earlier this year, was to procure an e-bike. (That's a bicycle with a motor, if you didn't know.) I could use it for commuting, for errands, for putting my human body to work, and for reducing my environmental impact. A cyclist I have never been, but perhaps an e-biker I could become. [...] But I've been trying to live with one, and brother, I've got some bad news. These things are freaks. Portraying e-bikes as a simple, obvious, and inevitable evolution of transportation (or even of bicycling) doesn't fully explain these strange contraptions. The same was said of Segways, and then of Bird scooters, and both flamed out spectacularly.

Bikes have always worn many helmets: cycling as exercise, cycling as leisure, cycling as sport, cycling as transit. These roles often conflict with one another. The commuter sneers at the spinner, who pedals pointlessly to nowhere. The leisure-rider spurs the Lycra-racer, who endangers pedestrians and inspires drivers to hate cyclists. E-bikes continue, and worsen, that disorder by jumbling up aspects of bicycles and motorcycles. Strapping a motor to a bike turns out to alter more than just speed and exertion. It produces a chameleon that takes on, under various conditions, both the best and worst features of a variety of transportation technologies. The result is less an evolution of a two-wheeled machine than a pastiche of the many things such a device represents. It's a monster made from bicycles and motorbikes.

Here's what I mean: A bike can be exerting to ride, which is both a feature and a defect. Biking to the store or office offers an opportunity to move one's body instead of spreading it into the seat of a car (or even a train). Depending on distance and terrain, biking can raise your heart rate, making it an effective workout. But working out can make you sweaty and smelly, a feature incompatible with using a bike for commuting (or even errands). E-bikes, by contrast, allow a motor to assist the rider, reducing exertion and thereby delivering you to the office or cheesemonger with a dry brow and dry armpits. But in exchange for that polish, an e-bike rider gets less exercise than the equivalent trip under full pedal. [...] The truth will differ based on circumstance, but the result is the same: a weird ambiguity. An e-bike sure seems like a way to cheat at exercise, even if it really facilitates it.

sdinfoserv writes: Yet another setback for automated driverless vehicle grail, Cruise recalls its robotaxis after a passenger was injured in a crash. The robotaxi was turning left at an intersection, assumed an oncoming vehicle would turn in front of it and stopped, resulting in the oncoming vehicle striking the robotaxi. A Cruise spokeswoman declined to say what the robotaxi could have done differently, and declined to release video of the crash. Nevertheless, Cruise said in a statement that it made the recall "in the interest of transparency to the public."

The company also said it's issued a software update to improve the ability to predict what other vehicles will do, including in conditions similar to the crash.

According to Twitter user @runews, someone hacked the largest taxi service in Russia, Yandex Taxi, and ordered all the available taxis to an address on Kutuzovsky Prospekt. The tweet includes a video showing the traffic jam that this caused in the middle of Moscow. It's not known who was behind the attack.

In a statement to SouthFront, the company said: "The security service promptly stopped attempts to artificially accumulate cars. Drivers spent about 40 minutes in traffic due to fake orders. The issue of compensation will be resolved in the very near future." The company stressed that in order to exclude such incidents in the future, "the algorithm for detecting and preventing such attacks has already been improved."

New submitter xwin shares a report from WTVO: With California's power grid under strain due to extreme heat and high demand, the utility grid operator is asking residents to avoid charging their electric vehicles. This comes days after the state announced a plan to ban the sale of gas-powered cars by 2035. The California Independent System Operator is asking residents for "voluntary energy conservation" over the Labor Day weekend.

According to the National Weather Service, the western United States is facing a "prolonged and record heat wave." "The top three conservation actions are to set thermostats to 78 degrees or higher, avoid using large appliances and charging electric vehicles, and turn off unnecessary lights,â the American Public Power Association said, asking residents to limit energy usage during 4 p.m. and 9 p.m. "Today, most people charge their electric cars when they come home in the evening -- when electricity demand is typically at its peak," according to Cornell University's College of Engineering. "If left unmanaged, the power demanded from many electric vehicles charging simultaneously in the evening will amplify existing peak loads, potentially outstripping the grid's current capacity to meet demand."
